The intersection of the Kamanashi River, upstream from the Fuji River, and the Midai River to join the Kamanashi River has been flooded since ancient times. Takeda Shingen(1521-1573), the load of this province, ordered the building of discontinuous embankments, instead of continuous embankments, to avoid the flooding. A water channel was created in the shape of a figure eight, a method of returning the flooded water back to the river.
On other hand, piling stones at several points upstream controlled the flow. Those methods were combined to avoid flooding. Wisdom is effort and ingenuity that harmonizes with Nature, great respectful things.

Noshiro faces the Sea of Japan. It originally appeared with the name of Nushiro, in 658 in Nihonshoki, the Chronicles of Japan. It was the place Abe no Hirafu, a Japanese general of the Asuka period (550 -710), visited along his conquest of the eastern area. It was recorded in 771 as the port of the envoys from Bokkai, established after the fall of Goguryeo (37 BC – 668) in the Korean Peninsula and Manchuria of the Northeastern China, by the alliance of Sila (57 BC – 935), during theTang Dynasty (618 – 907). The old name, Nushiro came from the Ainu language, meaning “grassland on the plateau”.
It’s strong winds blow constantly on the coast of Noshiro. The 24 power generators, in a row over 3km, create modern circulating power along the grassland.
